to much water flowing through shower valve will cause whistle in pipes.try a new shower head with less flow[gallons per minute]amount should be on head somewhere try 2.5 gpm or less
You have a washer or internal flow control device vibrating in the water stream. Generally not harmful, but if it's too annoying, try changing out your shower head.
A dog crys a high pitch whine when it is lonely. Dogs just want attention just like most people. Dogs have always whined since the beginning of time and they always will.
Hot water is spraying out into the atmosphere at high pressure. This causes condensation.
The difference in pitch.
Pitch (high and low)
Our Maine Coon sang (especially when we were in the shower) with a "trill" high pitch melody. It was fascinating.
One of the causes of a high-pitched whine during acceleration on a 1999 Nissan Maxima is a fan belt that might be a little too tight. A drop or two of any dish soap on the inside of the belt should cure the loud whine. If not, make sure all of the pulleys on the fan apparatus are turning properly.
When your fuel pump stops working so does your car you should hear a high pitch whine coming from the rear of vehicle when you turn the key to run
Have you checked the rear end fluid yet? Before jumping to a new rear, I would at least see how the fluid is in the rear end.
belt tension too high.
Depends. Do you always hear it or only when speeding up and slowing down. I have the same thing on mine but nothing is wrong with it. It's the transmission that's making the sound. Nothing to worry about unless you start to get a clunking or grinding sound, then you have problems...
In general, a low pitch is created by sound waves vibrating and having to travel down a lengthy object, while a high pitch only has to travel down a shorter distance
A high-pitched whine in a Dodge Dakota only when the weather is cold might be a normal thing. When the weather gets cold, the belts, starter and alternator need time to warm up. Try a little drop of dish soap on the fan belt to see if this helps quiet the whining.
